Problems solved by technology

[0002] At present, there is no text detection technology for passport stamps. For existing text detection in complex scenarios, the network input layer image is large, and the network structure is too complicated. However, the single stamp image of a passport is relatively small, and the background of the stamp text is relatively simple. Existing complex The text detection speed in the scene is relatively slow and not usable
The existing ID card text detection technology realizes positioning through the position of fixed elements in the template, but in the case of deformed, rotated, blurred and missing stamps, template matching is used to detect text, and the accuracy rate is not high
[0003] It can be seen that the existing seal text recognition scheme has the technical problem of low accuracy of text area positioning

Abstract

The embodiment of the invention provides a seal text positioning method and device and electronic equipment, and belongs to the technical field of image processing. The method comprises the followingsteps: receiving a to-be-identified seal picture; inputting the seal picture into a trained text region positioning model to obtain a site parameter of a text region in the seal picture, the site parameter at least comprising at least one of a vertex pixel, a head-tail pixel and a boundary pixel of the text region; and positioning the text area in the seal picture according to the site parametersof the text area. According to the scheme provided by the embodiment of the invention, the text region is automatically and accurately positioned in the to-be-identified seal picture through the trained text region positioning model, so that the identification efficiency and accuracy of the text region in the seal picture are improved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, in particular to a stamp text positioning method, device and electronic equipment. Background technique [0002] At present, there is no text detection technology for passport stamps. For existing text detection in complex scenarios, the network input layer image is large, and the network structure is too complicated. However, the single stamp image of a passport is relatively small, and the background of the stamp text is relatively simple. Existing complex The text detection speed in the scene is relatively slow and not usable. The existing ID card text detection technology realizes positioning through the position of fixed elements in the template, but in the case of deformed, rotated, blurred and missing stamps, template matching is used to detect text, and the accuracy rate is not high. [0003] It can be seen that the existing stamp text recognition scheme has the technic...
